6.3 Power regulation
The required delivery head is set by means of the rotary switch on
the pump terminal box (uniformly from p. ex. 1 ... max.
see imprint on cover).
Thanks to this inifinitely variable regulation, the pump can adjust
to the respective requirements of the system.
There is a risk of scalding
Depending on the temperature and system pressure, hot pump
medium can emerge in the form of liquid or steam.
- Never remove the screw plug completely –
the pump can suck in air.
Powerful escape of liquid.
- Switch the pump on and off 5 to 8 times until
only water emerges at the screw plug.
- Tighten screw plug.
- Increase system pressure again.
- Switch pump on.
6.2 Deaerating
Deaeration of the pump, in particular the motor area, is
implemented automatically after a short period of operation.
However, if very rapid deaeration is required, proceed as follows:
- Switch pump off
- Reduce system pressure to 0.5 bar
- Release the screw plug so far
(approx. one turn in an anti-clockwise direction)
until water emerges.
6. Commissioning/Operating check
6.1 General remarks
Fill the system correctly and deaerate it.
Only put the pump into operation when the plant has been filled.
